ABSTRACT:
A method for storing dial information regarding a previously dialed telephone number in a nonvolatile memory during an originating speech and for processing the dial information stored in the nonvolatile memory during a redial function. The method for use in a telephone having a redial buffer and a nonvolatile memory includes determining whether an originating speech is formed, storing the dial information representing a dialed telephone number of a called subscriber in a redial buffer, and storing the dial information of the redial buffer in a nonvolatile memory, so that a redial function can be reliably serviced even when the power supply has been cut off.
